Fields in production
The Alba oilfield, located in the central part of the UK North Sea, is operated by Chevron. We have a 17% interest in this field.
The Schiehallion oilfield is located west of the Shetland Islands. BP is the operator, and we have a 5.88% interest. In April 2010, the Schiehallion partnership approved the concept selection for the acquisition of a new FPSO vessel.
Jupiter is a gas field located in the southern part of the UK North Sea. We have a 30% interest and the operator is ConocoPhillips.
All these fields are in the mature to late-life stage of production.
Discoveries under appraisal
We are operator for Bressay (in which we have a 81.63% interest) and Mariner East (in which we have a 62% interest). In September 2010, we acquired an additional 20.67% in the Mariner Field, of which we are also operator, taking our total interest to 65.1%. They are all heavy oil discoveries for which studies and concept selection will continue.
Rosebank, a discovery made by Chevron in 2004, is located west of the Shetland Islands. We have a 30% interest in this field. The partnership is currently working on concept selection for field development.
